What is a Six Sigma Certification?

Bill Smith developed Six Sigma in 1986. Soon after that, an engineer developed a new approach based on quality control and statistical methods endorsed by Edward Deming, Walter Shewhart, and Ronald Fisher. This approach aimed to improve devices in an enterprise that did not match the industry’s quality standards. The methods used were as follows:

  • Edward Deming developed the sampling methodologies that the Census Departments and Bureau of Labor Statistics use even today.

  • Walter Shewhart was the first to come up with SQC (statistical quality control) and the PDCA (Plan Do Check Act) model.

  • Sir Ronald Fisher was responsible for popularizing many techniques for statistical analysis through his work. Some of the most popular ones are p-value, f-distribution, and t-distribution.

Ten Reasons to Earn a Six Sigma Certification:

1. Knowledge can be applied across multiple industry verticals:

Everyone knows that Six Sigma methods and processes work well within the manufacturing industry. However, what many people don’t realize is that this methodology also has applications across other verticals in the industries like IT, healthcare, telecom, banking, shipping, marketing, and HR, among others. 

When you have a Lean Six Sigma certification, you can expand the avenues and opportunities available for your quality control career. This certification standardizes your quality management skills and makes you a better prospect before recruiters, because of your skills and their applications across different industries. 

2. Key role in guiding enterprise efforts at reducing defects and errors:

The main reason why professionals choose a Six Sigma certification is to aid enterprises in reducing defects and errors in their processes. A certified Six Sigma professional helps businesses’ efforts at improving production costs and time. In the domain of information technology, knowledge of Six Sigma helps in reducing customer complaints, errors, slips in scheduling, and IT spending. Having a certification helps you stand out in a quality management team among those without an official credential.

3. Achieving a high rate of customer satisfaction:

Six Sigma helps reduce errors and increase efficiency. But more importantly, it can also be used for reducing customer complaints and issues. Business standards rely greatly on service quality, as it directly impacts the customer experience. This, in turn, increases or decreases customer loyalty. When your processes are risk and error-free, the customer experience can only get better. 

4. Improving business processes:

Any professional who earns a Six Sigma certification has a stronger understanding of an enterprise’s business processes. As a certified Six Sigma professional, you have the skills for measuring, analyzing, controlling, and improving these processes. You can also carry out essential reviews of the existing processes for a stronger understanding of how they impact the company’s offerings. Business organizations around the world hand-pick certified Six Sigma professionals who can help improve their business. 

5. Ensuring businesses adhere to government and industry standards:

In the global service-based market today, governments and enterprises apply Six Sigma metrics for reviewing vendors and awarding business contracts. With a Six Sigma certification, you become a part of this changing and expanding market. You can lead the quality management strategies within your organization and get the most out of business contracts across the public and private sectors. 

6. Optimizing and maximizing enterprise resource usage:

With a Six Sigma certification, you demonstrate to your organization the skills required for utilizing resources in the most optimum manner. As a result, your business costs reduce in terms of time, raw materials, and operational processes. By applying the Six Sigma technique, you ensure that lesser resources go into course correction and focus more on improving processes. This gives you fewer errors and defects and greater emphasis on sales and marketing. 

7. Standing out in the crowded, saturated market:

Once you have a Six Sigma certification and are hired by an organization, prepare to be at the front lines of everything within the organization. As a Six Sigma professional, you are responsible for initiatives aimed at improving internal processes within the company. Having a certification sets you apart from the rest of your team as it proves your skills to your team and employer. You are also now equipped to help businesses in implementing Six Sigma training and tools. This provides companies with a strong team of people who help in delivering efficiency transformation and enhanced performance. 

8. Taking on leadership positions:

Six Sigma offers certifications at different levels, varying based on the level of experience and expertise of the user. These levels are Yellow Belt, Black Belt, Green Belt, and Master Black Belt, which we will get into a little later. A Six Sigma certification prepares you with knowledge and expertise on Lean Six Sigma concepts and methodologies. You are thus equipped to drive change within your company and lead efforts at the enterprise level to improve service quality and services provided. A Six Sigma Master Black Belt credential makes you the premier candidate for a promotion to the senior management side and for getting a leadership role when the need arises.

9. Higher salary remuneration opportunities:

A Six Sigma professional is among the world’s highest-paid professionals in the IT industry and even other industries. Data released by PayScale shows that the highest annual salary for a Six Sigma professional in the US is about US$147,000 on average. This varies depending on your expertise and experience level. 

10. Differentiating your business from the competition:

Any enterprise with a dedicated Six Sigma certified team or workforce will inevitably have an advantage over its competition. A company’s primary stakeholders and decision-makers all know that Six Sigma methodologies are easily applicable for all their business processes. Organizations using Six Sigma as a part of their operation optimization strategies include Ford, GE, Toyota, and Motorola, among others.
